[PATCH] tee: optee: sync cache on pre-reloc OP-TEE invocation

2021-05-12 Thread Etienne Carriere
This change ensures both U-Boot and OP-TEE see the same content from shared memory when OP-TEE is invoked prior U-Boot relocation. This change is required since U-Boot may execute with data cahce off while OP-TEE always enables cache on memory shared with U-Boot. Signed-off-by: Etienne Carriere
